Account cancelled 6 months ago

<p>I cancelled my account on the 29th of December 2016. I am still being billed for this account. I contacted Telkom in March and got a response from a service manager:</p> <p> </p> <p>"Dear Dale</p> <p>I get the cancellation form thank you</p> <p>I'hv already escalate it to my supervisor</p> <p> </p> <p>THANK YOU". I have followed up 4 times since and haven't received a response. Please advise on how a person is supposed to cancel their account without being billed after that.</p>
